COIN-CONTRCLLED LOCK.

To all whom t may concern.'

'Be it known that l, Geenen G. F. Bos' ings.

The object of this invention is to provide an improved coin-controlledlock for cheek rooms, toilet rooms, telephone booths and 'thelike Thenature of the invention will be understood from the accompanyingdrawings and the following description and elaims.

'In 4the drawings, Figure 1 is an elevation of the front edge of thedoor and lock thereon, the upper and lower parts of the door beingbroken away. Fig. 2 is the outside elevation of the lock and the portionof the door attached thereto. Fig 3 is a sectitm on the line 3-3 of Fig.2 but on a larger scale showing the dilferent positions of the coin bydotted lines, and the partsl being shown in their operative. position.Fig. 4 isfa section on the line ljl- 4 of Fig. A 1 through the loek buton an enlarged scale7 and showing the lock in normal condition. Fig. 5is the same with the means for indicating and also controlling the eoinslotbeing omitted. Fig. (3 is a section on the line Fig. 7 a section onthe line 7*7 of. Fig. (3, showing the coin in the locking position. Fig.S is the saine as Fig'. 7 with the knob actuated and the boltwilhdrawn.'Fig-@ds a horizontal section on the line`9--9 of Fig. 1, through thelock and` a portion of the door and showing the parts in normalposition. Fig. l0 is the same as the central part of Fig. 7 with theparts in position after vthe door has been closed or locked and the coindiscliarged. F 11 is a section on the line 11--11 of Fig. t).

In detail, there is shown in the drawings a door 10 to which. there issecured a leek case 11 and t2 is the outside knob which is secured ontheknob shaft- 13 by a screw 14.

as shown in Fig. 3. The outer end of the knob shaft 13 has a tubularopening 15. The central part of the knob shaft has normally a vertifalslot 1G through it and the inner end of the knob shaft is likewisetubular and internally threaded to hold the Specication of LettersPatent.

adjusting screw 17. The knob shaft has a shoulder 18 which engages theinner surface outside of the easing so as to prevent the outwardwithdrawal of said knob shaft, and the screw 14- -has its head vlocatedin said tubular opening 15, and the body of the screw passes through areduced opening in the eXtreme outer end of the knob shaft, whereby itis impossible for anyone to re' move the knob from the outside. ln orderto operate the screw 14, the screw-driver is inserted through the doorand the knob.

shaft freni the inside before the adjusting screw 17 is in place andbefore the plug 20 hasbeen inserted in the opening through the doorwhich leads from the inner surface of the door through to a chamber 21therein. There is an enlargement of the knob shaft 22 which tits againstthe inner surface of the inner wall of the casing. The extreme inner endof the knob shaft is externally threaded for a nut 23 which lies in therecess 21 of the door. Therefore, the knob shaft cannot be moved ineither direction and it is firmly held in place in the walls of thecasing, and the knob shaft also holds the walls of the casing in placeand suitably spaced apart. The width of the coin .slot 16 in the knobshaft is modified by the screw 17 to suit coins of any denomination. Onthe inner half of said knob shaft within the easing there is a sleeve ortumbler 25 which has longitudinal slots 2G on the opposite sides of itto correspond and register with the coin slot 1G in the knob shaft. Saidtumbler and knob shaft have intkpemlent rotary movement limited 4by thelength of. the Aslot 126, see Fig. 10, through which the arm 27 from theknob shaft extends and to which the spring 2S is connected, said springextending downward and being secured at 29 to the inner wall of thecasing. The function of the spring 2S is to returnthe parts to theiriormal position after they have been operated.

There is a plate 31 secured to the inner wall of the casing andextending toward the outer Wall. To said plate 31 a counter 32 .issecured which projects through the opening in the end Wall of the casingand there discloses numerals indicating the number of times the leek hasbeen operated.Y The counter has a shaft 33 which is actuated by movementof the arm 34.

The tumbler 25 has 4a bolt-withdrawing casing 11 and 111. That portion45 inside arm '35 projecting radially therefrom, as shown in Fig. 5,with one surface curved in position to engage the pin 3G on the bolt 37and withdraw it when the knob 12 is turned. ,lVhen the spring 23 returnsthe parts to their normal position the arui 35 engages the shoulder 38of the bolt and throws it into locking position. The bolt is guided bythe usual opening in the end wall of` the casing` and also by lugs orprojections 39 and 4() on the inner wall of the easing, see Fig. Thebolt is held against the inner wall ot' the casing by the arm The returniiioveiiien't of the arm 35 is limited by the stop lug 30 which extendsfrom the inner wall of the casing, see F ig. 5.

In the outer wall ofthe casing, near the upper end, there is a coinIslot 40, see Fig. 3, through which va coin 41 may be inserted. Whensaid coin is inserted it extends through a slot 42 in a plate 43 whichserves to close and open said slot as well as to indicate when it isclosedor opened. Normally said slot in the plate 43 coincides with theslot 40 where` by the coin can be inserted.. The coin moves between twoparallel guide plates 44 which extend outwardly from the inner surfaceof the inner wall of the casing, as shown in Fig. 5, and extend down toa point lower than the bolt 37, but wherethey extend over the bolt 37they extend over so as not to interfere with the movement of the bolt;This coin chute forms vert-ical passageway for the coin, which registerswith the coin slots 26 and 1G in the tumbler 25 vand the enlargedportion of the knob shaft.

The inner knob shaft 140 is located somewhat above and to thev right ofthe outer knob shaft 13. Said shaft 140 has a squared vouter end fittinginto a corresponding slot in the inner knob 141 which is held on saidshaft by a sci-ew 142 against the shoulder in the` outer end of the tube143 through the center of .said knob shaft, as shown in Fig. 11. Thisshaft has rounded portions 144 thereon to form bearings in the walls ofthe the casing is square in cross section and/near the rear wall `111 ofthe casingA a finger 46 projects in a downward and-inward direc tiontoengage a lug. or projection 47 on the inner end of the bolt 37, andwill,` when thel inner knob is turned', cause the withdrawal Thatend ofthe shaft near the of the bolt. -out'er wall of the casing l1 is slottedto receive and hold, by means of the screw 48, a

piece ofsheet meta-l 49 similar in shape tov the ward of a key. Thisstrip is adapted toy clear the wallsof the casing andhas a projection 50concentric with the tube 143 and projecting even with thev end thereof,which projection serves as a pivot for the key which p thc casingl il,whereby the bolt may be withmay be inserted through the key-hole 51 indrawn without inserting' a coin iu the Slot- 40. The ward-like strip 49serves to engage H and move the plate 43 back to its normal position andopen the coin slot 40 whenlthe inner knob is tui-ned. The plate 43 ispivotally connected by the link 55 with'the arm 34 on the shaft of thecounter 32. plate 43 is nioved by the movement of the outer and innerknob, the caused to register.

A door :'iti at the lower front portion of the casing has downwardlyprojeeting lugs 58 on tliei'eai'side which will engage: a rim of th'ccasing, and by means ofa lock GOvronthe upper and iinieigiside of saiddoor the defer iii-ay be held in place in the front casing-1,1 and willlie flush with said casing.vr This counter will be Thus, as the dooraffords means, whereby the coins which and fall through the coin chuteinto the coin slot 16 of the knob shaft 13 where it will be held againstan edge on the lower side of said coin slot 16, as shown in Fig. 7. Whenthe outer knob 12 listurned,the edges of said coin-slot will pinchor'engage the coin, and by turning'the knob'fa-rther the coin will engage the edges of the slots through the tumbler'25 and the plate43and-will cause them to turn. Vthen the knob 12"l is turned to itsextreme position the'plate 43I will close the coin' slot and throw thelever 34( of ,the counter to the right, While the bwyltvi'thdrawing arm35 0n the tumbler 2553 vill cause the withdrawal of the bolt and allowthe'door to be opened. Upon releasing the knob the spi-i g 28 will causethe return of the bolt 37, the knob shaftand tumbler to their normalposit-ions and the coin will drop through the slot in the tuinbler25and' into the lower portion rof the lock case at the rear of the door56. But the plate 43 will not be returned to its normal position andwill keep the coin slot 40 closedfuntil the rear knob is turned. Thisaction will push the plate 43 t0 its normal position-and open the slot40 and will give the final or registering stroke to the arm 34 of thecounterl and cause'it to register. I
